Yamaha RX-A860 7.2 channel Aventage AV receiver + MusicCast offers tremendous power, superb performance, Yamaha’s advance Anti-Resonance Technology, MusicCast plus a phono input.
Speaker Layout Patterns
Multiple placement patterns are available for presence speakers that support Dolby Atmos & DTS:X, creating a sound field that’s ideal for your setup. Any layout can be appropriately reproduced, including the three-dimensional space of CINEMA DSP as well as both sound formats.
This AV receiver is compatible with many audio formats such as Dolby True HD and DTS-HD Master Audio. It is also compatible with high-resolution audio codecs such as DSD / AIFF / FLAC / WAV / Apple Lossless. You will enjoy the excellent sound quality of these various high-resolution audio codecs from the USB input on the front panel or from network connected devices.
The Aventage line of high-performance AV receivers is based on the audio design concept of providing a massive, full-bodied sound for movie sound effects and the accurate reproduction of music sources. By expertly harmonising traditional and advanced technologies, every factor that affects sound quality, from materials and parts to construction, layout, vibration damping (unique foot) and “fine-tuning” the sound, is handled with no other thought than to achieve the best possible audio quality. As a result, every Aventage model has the ability to reproduce the most subtle details of high-definition sound, so that listeners can enjoy a truly high-class sound studio experience at home.
The Anti-Resonance Technology Wedge is a fifth foot in the centre of the unit. It dampens vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers. This AV receiver was designed with a strong focus on achieving exceptionally high sound clarity. It employs a discrete amp configuration and a low jitter PLL circuit, which contribute to its excellent audio performance.
MusicCast makes it easy to bring music to every room in your home wirelessly with playback controlled by a simple app. Start with a MusicCast capable AV receiver in your main entertainment room for the ultimate home theater experience, then add MusicCast speakers, sound bars or Hi-Fi components in other rooms wirelessly. MusicCast allows you to access your digital music library, streaming music services and Internet radio, as well as Bluetooth sources, your TV sound and external sources attached to your AV receiver, such as a Blu-ray disc player or CD player.
Play your favorite streaming service. This AV receiver is equipped with Bluetooth functionality to let you enjoy easy wireless music playback from mobile devices. The Compressed Music Enhancer from Yamaha is now optimized for Bluetooth audio transmissions to ensure that your music will have vivid, lively sound quality during wireless playback. The RX-A660 is equipped with the latest Bluetooth technology, making wireless operation more convenient than ever. You can stream music from the RX-A660 to Bluetooth headphones for private listening or to Bluetooth speakers.
4K Ultra HD
This AV receiver completely supports with the latest HDMI standards. Thanks to transmission of 4K video at 60 frames per second pass-through, you can fully enjoy the high definition video quality of 4K without degradation. It also adheres to the HDCP2.2 copyright protection standard for 4K video transmission. It also supports HDR (High Dynamic Range) Video which provide enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. Furthermore it supports wider colour gamut of BT.2020 pass-through. 3D means the receiver can handle 3D signal data. The Audio Return Channel function enables data to be sent and received via the same HDMI cable, so you can hear the sound from the TV via a single HDMI cable, with no need for an extra optical cable.
21:9 Aspect Ratio
The 21:9 aspect ratio support is designed to show films recorded in the Cinema Scope format. When these films are viewed in the usual 16:9 ratio, you see black bars at the top and bottom of the screen; 21:9 eliminates these bars. By supporting 21:9 resolution, this model will be able to pass it through so that movies and games feel much more immersive.
Wi-Fi and Wireless Direct
Built-in Wi-Fi allows for a wireless connection with your wireless router, greatly simplifying system connections for enjoying networked audio (PC / NAS) and music streaming services. If a Wi-Fi router is not available, the unique Wireless Direct feature not only allows you to stream music directly from your smartphone or tablet via the AV Controller App, AirPlay etc., but also allows for control of the AV receiver as well.
This AV receiver provides a variety of network functions that enable you to access more sources and also enhance operation. You can connect the receiver to your home network or internet to enjoy Internet Radio, Spotify, Pandora or music stored on a NAS and home PC. The AV Controller app (from iTunes App Store or Google play) lets you control various functions from your iPod, iPhone, iPad or Android phones / tablets.
AV Controller App
Easy and convenient operation. This AV receiver lets you use the Yamaha AV Controller App that is downloadable from iTunes®, Google Play or the Amazon App store to control the power, volume, input selections, DSP modes and much, much more from an iPhone® or Android™ device. You can also use as many as 23 different languages and customize the interface by hiding unused icons and renaming functions. A tablet version is also available. This AV receiver provides Phono input terminals. Connect a turntable and you can enjoy music from your vinyl collection.
Human ears have less sensitivity to high and low frequencies, especially at lower volumes. YPAO Volume applies loudness EQ correction to automatically adjust high and low frequency levels as volume changes. Using the YPAO measurement results, EQ correction is optimised to your system settings and listening environment. YPAO sound optimisation analyses the room acoustics and adjusts various audio parameters for optimum sound in just a few minutes. It’s like having a professional installer calibrate your system.
Total Purity Concept, which Yamaha has been cultivating for many years, encompasses high drive amp technology, high purity preamp and anti-vibration technology. All models have fully discrete power amprs that help minimize distortion. They also adopt pure independent power supplies, allowing dedicated power supplies for the analog and digital circuitry to prevent digital noise from affecting analog circuitry.
The Virtual Presence Speaker function makes full use of centre and surrounds to create virtual presence speakers. This model also features a Virtual Surround Back Speaker function. Even without using surround back speakers, you can experience more natural sound from behind you.
The Virtual Cinema Front feature lets you place two surround speakers and a centre speaker at the front to enjoy virtual surround sound with even higher quality and resolution, as well as superior rear virtual sound localization. Adding two additional front presence speakers provides a three-dimensional sound field that gives you a feeling of its height and depth and of the vertical movement of the sound.
This exclusive low-range enhancement technology delivers richer bass than you would expect from smaller sized speakers while maintaining good localization and sound balance even with compact front speakers. When a subwoofer is used, it improves the volume of the entire low range of the speaker system, not only the front speakers, but also enhancing the bass from the subwoofer. You'll enjoy video and music with sound that has exceptional power and presence.
The Subwoofer Trim Control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused soundstage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is “pushed” toward the subwoofer. Subwoofer Trim Control takes care of this by separating the low subwoofer frequencies cleanly, thus stabilizing the front stage while providing a well-balanced enhanced bass sound.
When music is encoded into a digitally compressed format like MP3, the frequency response suffers. The Compressed Music Enhancer from Yamaha employs sophisticated digital signal processing using exclusive algorithms to restore what was lost, so the music always sounds the way it should. Many live and classical albums have no gaps in the music. Gapless playback ensures that there are no pauses between audio files. This provides playback with no interruptions, the way it was meant to be heard.
Intelligent Amp Assign
Automatically assigns amplifier channels to certain speakers, depending on what functions are selected. For example, in a 7.1-channel system, when Zone 2 is off, all 7.1 channels will be used in the Main Zone. However, when Zone 2 is on, power to the two Surround Back channels will be directed to the two speakers in Zone 2, and the Main Zone will receive 5.1 channels of power. Similarly, when CINEMA DSP 3D is on, the two Front Presence speakers will be powered and not the two Surround Back speakers.
